BACKGROUND:flight simulator have become an important component in pilot training. However, they are known to be associated with motion sickness like symptoms defined as Simulator Sickness (SS). Prevention countermeasures against motion sickness have been studied extensively focusing on cholinergic blockers and antihistamines. Most comparataive studies emphasized the effectiveness of scopolamine over outher agents. Evidence, though, on prophylaxis against SS is sparse.

OBJECTIVE: to assess the effectiveness of oral scopolamine versus oral cinnarizine or placebo for SS prevention in helicopter pilots.

Finding more effective treatment to the motion sickness symptoms during and after simulator training. [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]

To record a significant difference in motion sickness symptoms reduction during and after simulator training, after taking cinnarizine, scopolamine or placebo. We predict that scopolamine will prove to be more effective than cinnarizine with fewer side effects that can compromise pilot's performance during training.
